Question 295

Which of the following is true about the principle of Huawei Oceanstor V3 smart cache: (multiple choice)

When an IO arrives at the storage system, in order to avoid affecting the write performance, the data in the smart cache will not be any changes due to the IO

When reading the data in the missing smart cache, the smart cache pool directly forwards the read IO request to the HDD

If OceanStor V3 is shared between services A and B, the same custom smart cache partition can be used

The system generates a default smart cache partition for each controller by default

Question 296

Which of the following is correct about the InfoStamper feature of an OceanStor 9000 storage system: (multiple choice)

Snapshot does not support nested, that is, the snapshot has been created directory, the parent directory and subdirectories can no longer create a snapshot

The root directory of the snapshot (that is, the directory used to create the snapshot) does not support deletion

Hard links are protected by snapshots, soft links are not protected by snapshots

For a snapshot with an expiration time set, the system automatically deletes the snapshot but does not back up the storage space occupied by the snapshot data after the snapshot expires

Question 298

Which of the following is a description of the WORM feature of OceanStor V3: (Multiple choice)

When the file is in an append state, after the legal clock of the WORM file system exceeds the file expiration time, the file is movedMoved to expired status

When the size of the file is 0 bytes, the lock state can be migrated to the additional state

Question 299

A computer center plans to purchase a set of Huawei Oceanstor 9000 products as a follow-up storage system. The requirements are as follows:

(1) The minimum storage system needs to provide a total bandwidth of 3-4GB / s

(2) storage space can reach 1PB, to meet a single file GB storage

(3) computer center room requires control deployed in a cabinet use

(4) Internal computer cluster nodes are now all InfiniBand network

Based on the above information, which of the following configuration suggestions do you think is more suitable for this project?

Because computing tasks are designed for large file services, it is more appropriate to deploy with an 8-node OceanStor 9000 C node. The capacity on the use of 4TB SATA, to meet customer needs

Using Oceanstor 9000 C Node combined with the total bandwidth and total capacity requirements, consider the 8-node configuration 4TB SATA full disk, backend 10GETOE + front-end IB networking

From the reliability point of view, it is recommended to use the InfoEqualizer function to access the OceanStor 9000 storage through a domain name. The InfoEqualizer DNS segment needs to be considered and OceanStor 9000 back-end to interoperability

OceanStor 9000 supports front-end 10GE TOE + back-end IB networking, the front-end is easy to log in and manage with the management PC interworking, considering this networking solution can reduce the cost of front-end IBswitches.
